Abstract

本发明公开了一种加固型的道路防护栏，立柱通过连接支架固定连接有防护栏，防护栏由两块相对并呈弧形的前栏板和后栏板组成，前栏板的上、下两端分别和后栏板上、下两端固定连接，前栏板和后栏板之间成型有椭圆形的槽腔，前栏板和后栏板之间的槽腔内插接有梯子形状的加固件，加固件包括两根水平的圆钢筋，两根圆钢筋分别抵靠在前栏板和后栏板上、下两端的弧形内壁上并通过焊接固定于前栏板或后栏板，圆钢筋之间设有若干竖直的拉簧，拉簧的两端焊接固定在圆钢筋上。本发明结构简单，采用相对的弧形栏板组合，既能提高防护栏的强度，同时约束了弧形栏板的上下侧边，增强了栏板弧形部分的弹性变形能力，从而提高防护栏的缓冲效果。

Description

一种加固型的道路防护栏
技术领域：
本发明涉及安防产品的技术领域，更具体地说涉及一种加固型的道路防护栏。
背景技术：
现有道路旁的安全防护栏的防护结构一般为防护板，防护板大多由金属材料折弯形成弧形板结构，弧形板结构的可以提供一定的缓冲力，以减小撞击伤害，但现有的防护板一般由单层的金属板组成，其防护板强度较低，则撞击过程起到的缓冲效果差，同时撞击力度较大时，无法阻止车辆冲出道路。
发明内容：
本发明的目的就是针对现有技术之不足，而提供了一种加固型的道路防护栏，其结构简单，提高安全防护栏的强度和缓冲效果。
为实现上述目的，本发明采用的技术方案如下：
一种加固型的道路防护栏，包括立柱,立柱通过连接支架固定连接有防护栏，防护栏由两块相对的前栏板和后栏板组成，所述前栏板和后栏板为竖直的金属板，金属板的上、下两侧弯折成型有弧线板，前栏板的中部和后栏板的中部焊接固定在一起；前栏板的上、下两端分别和后栏板上、下两端固定连接，前栏板和后栏板之间成型有椭圆形的槽腔，前栏板和后栏板之间的槽腔内均插接有梯子形状的加固件，加固件包括两根水平的圆钢筋，两根圆钢筋分别抵靠在前栏板和后栏板之间槽腔上、下两端的弧形内壁上并通过焊接固定于前栏板或后栏板，圆钢筋之间设有若干竖直的拉簧，拉簧的两端焊接固定在圆钢筋上。
所述连接支架呈“匚”字形，连接支架固定于后栏板的中部，连接支架的两端焊接固定在立柱的外壁上。
所述的连接支架焊接固定在相邻的两块后栏板上。
所述圆钢筋上成型有挂钩，拉簧的两端挂置在圆钢筋的挂钩上，拉簧均匀分布在圆钢筋上。
所述加固件位于相邻防护栏之间的圆钢筋为整根钢筋。
本发明的有益效果在于：
它结构简单，采用相对的弧形栏板组合，既能提高防护栏的强度，同时约束了弧形栏板的上下侧边，增强了栏板弧形部分的弹性变形能力，从而提高防护栏的缓冲效果。
附图说明：
图1为本发明立体的结构示意图；
图2为本发明侧视的结构示意图；
图3为本发明无前栏板的正视结构示意图。
图中：1、立柱；2、前栏板；3、后栏板；4、连接支架；5、加固件； 51、圆钢筋；52、拉簧。
具体实施方式：
实施例：见图1至3所示，一种加固型的道路防护栏，包括立柱1,立柱1通过连接支架4固定连接有防护栏，防护栏由两块相对的前栏板2和后栏板3组成，所述前栏板2和后栏板3为竖直的金属板，金属板的上、下两侧弯折成型有弧线板，前栏板2的中部和后栏板3的中部焊接固定在一起；前栏板2的上、下两端分别和后栏板3上、下两端固定连接，前栏板2和后栏板3之间成型有椭圆形的槽腔，前栏板2和后栏板3之间的槽腔内均插接有梯子形状的加固件5，加固件5包括两根水平的圆钢筋51，两根圆钢筋51分别抵靠在前栏板2和后栏板3之间槽腔上、下两端的弧形内壁上并通过焊接固定于前栏板2或后栏板3，圆钢筋51之间设有若干竖直的拉簧52，拉簧52的两端焊接固定在圆钢筋51上。
所述连接支架4呈“匚”字形，连接支架4固定于后栏板3的中部，连接支架4的两端焊接固定在立柱1的外壁上。
所述的连接支架4焊接固定在相邻的两块后栏板3上。
所述圆钢筋51上成型有挂钩，拉簧52的两端挂置在圆钢筋51的挂钩上，拉簧52均匀分布在圆钢筋51上。
所述加固件5位于相邻防护栏之间的圆钢筋51为整根钢筋。
工作原理：本发明主要为道路防护栏，采用两个相对的护栏板(前栏板2和后栏板3)焊接固定，两个护栏板能增强防护栏的强度，同时其护栏板上的弧形板部分的弹性变形能力也增强，同时又设置加固件5，加固件5上的圆钢筋51增强相邻防护栏之间连接强度和防护栏本身的抗弯折强度，并设置拉簧52约束护栏板上的弧形板上下侧边，亦能增强弹性变形的能力。
